To all whom it may concern:

Be it known that I, WILLIAM H. CooLnY, a citizen of the United States, and a resident of Brock ort, in the county of Monroe and State of l ew York, have invented a new and Improved Machine for Cutting and Corrugating Sheet Metal, of which the following is a specification.

This invention relates to machines for cutting sheet metal pre aratory to expanding the same, and embo ies also a corrugating mechanism, whereby the cut and corrugated sheet may be expanded by mechanism engaging the keys or bonds and drawing such keys or bonds in straight lines for the purpose of simplifying the expanding process.

In accordance with my method of producing expanded sheet metal, inasmuch as the expansion is effected by drawing the bonds or keys of the out metal in parallel lines transverse to the direction of thefeed of the metal through the cutters, it is necessary that the expanding process be effected by an apparatus or machine separate from the cutting mechanism, and in order to reduce to the minimum the number of interruptions in the operation of the expanding mechanism for the production of a given uantity of metal, it is important that the s eets be as Wide as practical transversely of the direction of the cuts and of the feed through the cutters. This necessitates cutting rolls of considerable length which, unless sustained at points between their bearings, would be apt to sprin if made of reasonably moderate slzc. I pre er to make such cutting rolls of moderate size and to support them by sustaining rollers adapted to bear upon and support the cutting rollers at points "between their bearings. In the use of such sustaining rollers it is important that the extreme outer peripheries of the cutting rollers be complete and uninterrupted cylindrical surfaces. For that reason I have devised built up in sections,

I have found that only one pair of such cooperating cutting rollers is necesa In practicing my processor method of forming expanded metal, in order that the cut or slashed sheet metal may be en aged at the keys or bonds and such bonds ra'wn in straight lines, in accordance with my present invention, I make use of rollers to form corrugations in the out metal extending in directions transversely of the direction of the cuts and of the feed through the cutters, such corrugating rollers (positively driven with the cutting rollers an at such a rate of speed as to cooperate therewith and with the rollers for feeding the metal thereto and therefrom.

The accompanying drawings show only such parts of a machine embodying my invention for cutting and corrugating sheet metal as are necessary to illustrate my inventionand, so far as possible, unimportant parts are omitted and other parts are shown diagrammatically. Such drawings are as follows Figure 1 is a side view of a part of the machine. the machine taken along the line a:y of Fig. 1, looking in the direction of the arrow. Fig. 3 shows cooperating segments of the corrugating rolls. Fig. 4 shows diagrammatically the arrangement of the feed rolls,

Fig. 2 is a sectional view of a part of cutting rolls and corrugating rolls. Fig. 5

shows a portion of .the cutting rolls and a strip of metal as passing therethrough and being acted on thereby. Figs. 6 and 7 show in views similar to Fig. 5 the action of different cutters upon the metal. Fig. 8 is an end view of the cutting rolls with parts of the same broken away. Fig. 9 is a vertical central section of the lower ortion of a part of the upper cuttin roll and the up or ortion of a part of. the ower cutting ro 1g. 10 shows diagrammatically .a strip oiithe metal as out before being corrugated, while Fig. 11

shows this same strip of metal after it has been corrugated.

Similar letters refer to similar parts throughout the several views, in which Figs. 3, 5, 6, 7, 9, 10 and 11 are drawn to a larger scale than Figs. 1, 2, 4 and 8.

Referring to the drawings,a mach ne embodying my invention may have side frame pieces A, each of which may have suitable supporting members, not shown, and they may be gether by means or cross pieces also not shown. Each side member A carries bearings for-shafts P, P, 1), 19 29 p 0 and 0 On the shafts P and P are assembled the cutting disksto form the cutting rollers C and O located between the side members A,

roperly connected to- 50 through the machine and of the direction of while outside of such side members A there are secured on these shafts P and P the intermeshing gears G and G The gear G meshes with spur gears g and g revolubly supported on studs 8 extending outwardly from and secured in the side member A. These gears g and g mesh respectively with the gears g and g secured on the shafts p and 11 while such gears g and g mesh respectively with the gears g and g secured on the shafts p and p On the shafts 2 and p are rigidly secured the feed rolls F and as seen in Fig. 2. Similar feed rolls F and F are secured on the shafts p and p to constitute another set of coacting feed rolls, which, by means of the gearing connections just, above described, are driven from the gear G On the shafts 0 and 0 are secured respectively the upper and lower corrugating r0 s T and T located between the sides of the machine, while on the side of the machine towards the observer there are secured on such shafts o and 0 intermeshing gears G and G respectively. The gear (5: is drivenfrom the gear G by the intermediate gear wheels G 9 and 9 revolubly supported respectively on the studs s, s and s The machine may be operatively driven by power applied to either of the shafts P or P. The gear connections between the several co-acting revoluble parts thus far described are such as to cause the proper relative rotations thereof to secure the cooperations hereinafter described.

The sheet of metal m to be cut and corrugated is fed from left to right through the,

machine and engaged first by the feed rollers F and F and advanced thereby into engagement with the cutting rolls 0 and C the construction of which will be described later,

gagement with and between the corrugating rollers T and T operating tocorrugate the metal transversely of the direction of its feed the cuts in such a way that a longitudinal section thereof will conform to the side bars anded metal.

lying between two adjacent and correspondingly disposed series of meshes in the ex- The corrugating rolls T and v 1 are so proportioned and spaced relatively to the cutting rolls and the rate of rotation of such corrugating'rolls T and T is also such that the crests of the corrugations formed thereby arearran ed along and in the lines of the keys or onds connecting thebars in the ex anded metal.

The cutting r0 ers C and C ,.as indicated in Figs. 5, 6, 7, 8 and 9, to which reference comprises similarly a series of plain disks a? spaced apart by substantially a distance equaling thrice their thickness. Between each two adjacent disks a are located, start-v ing at the eft, first a cutter c and then a spacingdisk d and then another cutter 0, while similarly between each two adjacent disks a -are located, first a cutter c and then as acing ,disk d and then a cutter c these dis s and cutters being so spaced and located on their respective shafts that two cutter disks on one shaft with a plain disk between them engage between two plain disks on the other shaft, and op osite each plain disk on one shaft is located a spacing disk on the other shaft. The plain disks are of such a diameter that they overlap each other at' their peripheries by substantially just twice that amount which the metal is to be displaced from the initial plane thereof at the deepest points in the cuts, as indicated in Fig. 5.

The diameter of the cutter disks c and c at their outermost points is substantially the same as that of the plain disks a and a. The

cutter disks 0 and c are so arranged angularly that the maximum diameter of a cutter 0 comes opposite a point midway between two adjacent points of maximum diameter in the cutters c and vice versa. There is, however, left between the two oppositely positioned cutters c and c a s ace amply sufficient for the free passage etween them of the metal m. The cutting projections on the cutters c and 0 may be arranged and conformed substantially as shown in Figs. 5, 6 and 7. The cutter disks of one cutting roller shear or cut the metal against; the ad acent edge and face of a plain disk in the other roller. The result of this arrangement is that the cutters c and cooperating with the plain disks 0, and a respectively cut the metal in the manner clearly indicated in Figs. 5, 6, 7 and 10 and more fully described,

stantially the thickness of such plain disks and the plain disks a force upwardly from the initial plane of the metal strips 3, the

width of each of which is substantially the thickness of such plain disks (1 and between each such strips of'the metal forced down wardly below 1ts initial plane and the adjacent strips forced upwardly from the initial plane of the metal there are formed a series of connecting bars 2 and 4 joined to the up-" such strips extendi per strip and to the lower stri at points denominated keys or bonds in the cut and exl panded metal. Each cooperating pair of cutters c and c are arranged to leave uncut portions or bonds in the metal between or i opposite the centers of the cuts formed by an 5 adjacent. cooperating pair of such cutters, as indicated diagrammatically in Fig. 10. The 1 result of this is that there is formed in the cut metal series of strips 1 extending continuj ously below the initial plane of the metal and series of strips 3 extending continuously above the initial plane of the metal and i ng continuously above are connected to those strips extending continuously below by intermediate strips 2 and 4 of equal width connected to such first named strips at alternating points, as indicated in edge view in Fig. 5.

The metal as it leaves the cutting rolls passes through the feed rolls F and F and f between two guide bars I) and b and is e11- j gaged by the corrugating rolls T and T which bend the metal to and fro, as indicated at m in Figs. 3, 4 and 11, the crest of I each corrugation being flattened and extending along the lines of the keys or bonds insuch a way that adjacent transversely arranged rows of keys or bonds are forced in opposite directions. The assembled disks comprising the cutting rolls are held in place by nuts n engaging against collars a.

At the top of the machine is seen a cross piece B and between the side members is seen a cross piece B. The cross piece B carries thereon brackets u extending both forwardly and to the rear therefrom to constitute bearings for the shafts 0 having thereon rollers V engaging against the plain disks a in such away as to sustain and support the upper cutting roller C to prevent the same from being forced upwardly by the thrust exertednthereon in cutting the metal. Similarly, the connecting piece B carries arms a forming bearings for the shafts 0 having thereon rollers V which similarly engage against the plain disks (1 on the lower cutting roller C Attention is especially called to the fact that in the metal as it leaves the cutting mechanism, the strips between the series of interrupted cuts are bent or forced from the original plane of the metal in such a way that the sheet is so shortened in the direction of the cuts that it may, at this stage, be ex panded by engaging the sheet at the keys and drawing the keys in straight lines transversely of the cuts. For the purpose of my present invention, however, I prefer to corrugate the sheet in the manner described, and before corrugating it, to flatten it out in order that the sheet may be more readily and satisfactorily corrugated, as the expanding, apparatus may be made of a preferred form lbs-tween the series whenthe metal is thus corrugated before it is expanded, although for expanding the metal as it leaves the cutters a modified form of the expanding machine which I make use of may be employed.
